Doesn't the Wilga have shutters in front of the engine which you can close
to prevent shock cooling during a rapid descent?

Yes, most if not all airclubs in Eastern Europe use Wilga as a towplane. The
aircraft was specially built for this purpose. The rear window and the
flying atitude of the aircraft allows excellent visibility for the glider
behind.

It was built to be a STOL (short take off and landing) aircraft, and the
wings are having slats for this purpose. It is able to tow your glider from
a 200 yeards field. With good headwind, the aicraft can take off within 100
feet run only!
It is not very well suited for air tours, because it has a glide ratio of
only 1/4. Its main strengths are climb and landing as fast as possible, in
other words, putting as much gliders as possible in the air.

When the engine is cut off, you can put the aircraft nose dive and bring it
to the ground within 2-3 minutes from an altitude of 2000 feet, without
being being worried about exceeding the maximum speed. Shorter time = less
fuel spent.

When towing, its fuel consumption is of approx. of 60 liter per hour.
Probably the best towing aircraft in the world.
